The AP fact checks Obama’s speech on Libya. For instance, regarding his claim that the US is handing operations to NATO:

The United States supplies 22 percent of NATO’s budget, almost as much as the next largest contributors – Britain and France – combined. A Canadian three-star general was selected to be in charge of all NATO operations in Libya. His boss, the commander of NATO’s Allied Joint Force Command Naples, is an American admiral, and the admiral’s boss is the supreme allied commander Europe, a post always held by an American.
